The work presented here concerns the evaluation of the reactivity of the [Ti8O8(OOCCH2But)16] cluster towards phenol, resorcinol and catechol using NMR techniques. Whereas the reactions conducted in the presence of phenol and resorcinol showed to be particularly slow, it appeared that catechol allowed the quantitative displacement of the carboxylato ligands. Upon addition of a large excess of catechol, a complete transformation of the [Ti8O8] core was noticed leading to final products formulated as Ti2(cat)4(L)2 (L = DMA, DMF).
